Expression of Apoptotic Signal Proteins in Children with Idiopathic T hrombocytopenic Purpura and Its Clinical Significance / 实用儿科临床杂志

ABSTRACT

Objective To investigate the exprestion of apoptotic signal proteins(FADD,Fas,FasL and NF-?B) in peripheral blood T lymphocytes in idiopathic thrombocytopenic purpura (ITP) children and its correlation with clinical outcome.Methods Collecting aseptic peripheral blood from ITP children (n=35) and healthy children (n=30), T lymphocytes were isolated and purified by the T cell Segregation Enrichment Column, Fas,FasL and T cell apoptosic ratio were detected by FCM. Immunohistochemical staining was used to detect the level of NF-?B and FADD.Results The expression rates of Fas,FADD in ITP children decreased,but the expression rates of FasL,NF-?B increased.The differences between ITP children and heathy children had statistics significance(P
